AUTOMATIC SWITCH FOR ELECTRIC OR CABLE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 545,230, dated August27', 1895.

Application filed December 12, 1894. Serial No. 531,56 i. (No model.)

To all whom it may concern:

Be it known that we, GEORGE T. JANVRIN and FRANK J. CONLON, citizens ofthe United States, and residents of Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inAutomatic Switches for Electric or Cable Railways, of which thefollowing is a specification.

Our invention comprises improved means for automatically operating theswitch by means on the car subject to the control of the engineer,wherebyit is designed to provide more GifiGlQDt, simple, and cheaperswitch apparatus of this kind, as hereinafter fully describecl,refereneebeing made to the accompanying drawings, in which Figure 1 is a planview of part of a track having a branch with a switch arranged inaccordance with the invention. side view of the apparatus of Fig. 1 anda section of the walls of the pit below the rails, in which some of theapparatus is arranged.

On each side of the main track a, and preferably outside of the rails,but in close proximity to them, is a vertical push-stud b, suitablyarranged in a vertical guideway c for vertical movement of about aninch, more or less, and so that the head will be level with the top ofthe rails when at the limit of the down movement and will otherwiseproject above the rails, so as to be thrust down by rolls carried on thecar and adapted to be let down on the rails by the engineer when theswitch is to be shifted, the car being provided with such a roll on eachside, adapted to be operated independently of each other. In the spacebelow the rails these push-studs connect with roclnlevers, through whichand suitable rods the switch-points, as d, having studs, as f, pendentin the space, are to be shifted by thrusts imparted to said pendants.

The stem of the push-stud b is connected with one arm of the elbowr0ck-lever h, pivoted at c and having its other arm coupled with theconnecting-rodj, which is also coupled with one arm of an elbowrock-lever k, pivoted at Z and having its other arm bearing against thependent stud f of the switch-point, so as to shift the point in onedirection when the push-stud b is thrust down, each pushstud i) beingsimilarly connected with the pendent stud f of the switch-point, but onop- .posite sides, respectively, so as to shift the Fig. 2 is apoint inopposite directions and so that when one push-stud is thrust down toshift the point one way the other push-stud will be thrust up by thereverse action of the point pendent on it, ready for reversing the pointj rock-levers and the convergent connectingrods is such that, while thepush-studs are on opposite sides of the track and the switchpoint at oneside, the connections are effected with very simple and inexpensive, buteffective, apparatus.

lVe claim- The combination with the switch point having a rigid pendentstud fprojecting into the space below the rails, and with a push stud I)located at each side of the main track and adapted to be thrust downindependently by rolls on the car subject to the control of theengineer, of an elbow lever it connected to each push stud, a connectingrod j coupled with each rock lever, and a rock lever k, coupled witheach rod respectively, and respect ively located on opposite sides ofthe pendent stud and bearing on it, suitably to push the switch pointeither way according as one or the other of the push studs isactuated,the said rods connecting the rock levers of the push-studs withthe point actuating levers, being suitably convergent to connectdirectly with the push stud levers at the opposite sides of the trackand with the point actuating rock levers located relatively thereto allsubstantially as described.
